Easy-operated bottles

ABSTRACT

A bottle which bottom has a female pattern which is a recessed space which can engage with an inserted male pattern which protrudes from the top of a cap; a bottle which bottom has a recessed space which cross-section resembles this of a cap and which can engage with an inserted cap; and a bottle which bottom has a female pattern which is a recessed space which cross-section resembles this of a cap which has a male pattern protruding from its sides and which can engage with the male pattern of the cap.

BACKGROUND OF THE INVENTION

1. FIELD OF THE INVENTION

This invention relates to easy-operated bottles and particularly tobottles with screwed on/off caps that can engage with shapes on thebottoms of other bottles to provide additional twisting arms forgenerating additional torque to facilitate easy opening/closing of thebottles.

2. DESCRIPTIONS OF THE PRIOR ARTS

No prior art related to easy-operated bottles was found.

SUMMARY OF THE INVENTION

Ordinary bottles have relatively small diameter caps. When twisted on oroff of the caps, much force is needed because the momentum arms arerelatively small due to the relatively small diameter caps. Therelatively small diameter caps are hard to be handled by hands. This isespecially true for those who have relatively weak hands or injuredwrists. For these people tools can be used to operate the caps. But,tools might not be readily available when needed. Therefore, easy waysto operate the bottles are sought.

The invented devices involve modifying the caps and the bottles so thatwith two bottles the caps can be easily twisted on or off. Specifically,each bottom of the invented devices will have a recessed space which canengage with a cap of another invented device. When two bottles of theinvented devices are stacked together, the bottle above will help thebottle below to twist on or off its cap. The user can handle theoperations of the bottle easily because the user will not have to handlethe relatively small cap directly,

These and other objects and advantages of the invention, as well as thedetails of an illustrative embodiment, will be more fully understoodfrom the following specification and drawings, in which:

GENERAL DESCRIPTION

Three variations of the invented device are introduced herein in thisspecification.

Referring to FIGS. 1 and 2, the first variation of the inventedeasy-operated bottle, 1, is a bottle which cap, 2, has a male pattern 4which consists of short plates extruding from the top of the cap. On thebottom, 3, of the bottle is a female pattern, 5, which consists ofrecessed areas which can engage with an inserted male pattern of a cap.

Referring to FIG. 3, when opening the cap of the invented device, theuser will firstly stack two bottles, 6 and 7, together. The user willhave the male pattern of the cap of the bottle at the bottom to engagewith the female pattern on the bottom of the bottle at the top. The capof the bottle, 7, at the bottom is the one to be opened. Then the userapplies some forces, 8 and 9, to keep the two bottles together and theuser then twists the two bottles in the directions shown as 10 and 11.Because the diameter of the body of the bottle is much larger than thatof the cap, additional torque can be generated using the same amounttwisting forces due to the extra moment arm provided by the body of thebottle. Therefore, the cap of an invented bottle will be easy to open.Furthermore, the bottle will be easy to hold for a person with weak orinjured wrist.

To close the cap tight, the user will firstly stack two bottles togetherwith the cap of the bottom bottle already being loosely screwed on. Theuser will have the male pattern of the cap of the bottle at the bottomto engage with the female pattern on the bottom of the bottle at thetop. The cap of the bottle at the bottom is the one to be tightened.Then the user applies some forces to keep the two bottles together andthe user then twists the two bottles to tighten the cap.

Referring to FIGS. 4 and 5, the second variation of the inventedeasy-operated bottle, 12, is a bottle which cap, 13, has an outsideshape resembles this of a nut, 15. On the bottom, 14, of the bottle is arecessed space, 16, which has similar cross-section shape of this of thecap and which can engage with a cap when the cap is inserted in therecessed space.

Referring to FIGS. 6 and 7, the third variation of the inventedeasy-operated bottle, 17, is a bottle which cap, 18, has a male pattern,20, which consists of short plates extruding from the sides of the cap.On the bottom, 15, of the bottle is a recessed space, 21, which hassimilar cross-section shape of this of the cap and which can engage witha cap when the cap is inserted in the recessed space.

The uses of the second and the third variations of the inventedeasy-operated bottle are similar to aforementioned processes for thefirst variation and will not be repeated herein.

The foregoing is considered as illustrative only of the principles ofthe invention. Furthermore, since numerous modifications and changeswill readily occur to those skilled in the art, it is not desired tolimit the invention to the exact construction and operation shown anddescribed, and accordingly all suitable modifications and equivalents,may be resorted to, falling within the scope of the invention asclaimed.

1. An easy-operated bottle consists in combinations of: a) a bottle anda cap; b) said cap having a male pattern protruding from the top; c) thebottom of said bottle having a female pattern which is a recessed spacewhich cross-section resembles this of said male pattern of said cap; d)said male pattern of said cap being able to engage with said femalepattern of said bottle when said male pattern is inserted into saidfemale pattern.
 2. An easy-operated bottle consists in combinations of:a) a bottle and a cap; b) the bottom of said bottle having a recessedspace which cross-section resembles this of said cap; c) said cap beingable to engage with said recessed space when said cap is inserted intosaid recessed space.
 3. An easy-operated bottle consists in combinationsof a) a bottle and a cap; b) said cap having a male pattern protrudingfrom the sides; c) the bottom of said bottle having a female patternwhich is a recessed space which cross-section resembles this of saidcap; d) said male pattern of said cap being able to engage with saidfemale pattern of said bottle when said male pattern is inserted intosaid female pattern.
